We're aware of an issue with converting some DOC, DOCX, ODT, and RTF files to EPUB through our Ebook Wizard.
We've created this Forum Thread with some workarounds and advice to assist you in publishing you ebook.

It's the yellow Use This Spotlight Name button. When you press it, nothing happens. You're just stuck on that screen. I am also trying to set up my author spotlight and it hasn't worked since last night.

I assume you have published something? If so then click the My Lulu tab. Look in the Project list. Click the title of what you have published. Look on the page that opens for Availability / Project Status: and there you will see the URL of your book on your Spotlight.

I am trying to create an author spotlight, too. Having the same problem as the others here. When I put in what I want to use and click CHECK nothing happens. Of course, until the Check is done, the yellow Use This Spotlight Name button is not useable/available.
